![[Runtime] Frelux Synergy2](https://precogvision.com/wp-content/uploads/2020/01/cropped-IMG_2940-scaled-3.jpg)
| Parasitic drain from OFF: 2.7uA |
| About 75 years to drain (2) Vapcell 14500 batteries. Consider it negligible. |
| Reed Instruments SD-1128 Light Meter |
| Room temperature with no cooling |
| All measurements are taken at “max” output |
| 30 second intervals for AA, 10 second intervals for 14500 (I thought 14500 would die faster) |
| Comments: 14500 looks ideal with this flashlight. Significantly more output and a good deal of runtime in-between standard Eneloops and Eneloop Pros. I don’t recommend either standard Eneloops or Alkaline AA. |
